At least some drivers need a full modeset to change the Colorspace
property or to en-/disable HDR mode. E.g., at least amdgpu-kms as
tested under Linux 6.8 on Polaris needs it. Otherwise the atomic
commit for disabling HDR in _wsi_display_cleanup_state() will fail,
and the connector stays stuck in HDR mode after vkDestroySwapchainKHR().
Fixes: 1ed78dd7ec ("wsi/display: Clean up DRM hdr/color state on swapchain destruction")
